Last August, after much research, I purchased a Titan MX with a 54 inch mulching deck to replace my 1994 Toro 4-16-8 Garden Tractor. It is my first ZTR mower so it took me a while to get used to driving it.
When I stored it for the winter, it had about 12 hours of use. On May 2nd of this year, I was going to mow and when I turned the key, nothing happened. Fortunately, I still have the 4-16-8 so I was able to get my yard cut.
I called the dealer and they came out and picked up my mower. After 20 days (waiting to get a replacement battery from Toro), they returned it and told me that Toro has had issues with batteries but they had given me a new battery and I was "good to go".
After about 21 more hours of use the same problem is back! This time, I took the battery to a dealer and they said it was run down, but still good. I recharged it and the mower is working again. Needless to say, the dealer has it again and is searching for whatever is draining the battery.
I also installed a Femco sunshade, but the ROPS bar is tilted forward so my shade is also tilted. It still works, however---unlike the mower!
